Plunger Lift

The DCS-NG (Differential Control System - Next Generation) typically operates by monitoring of the casing pressure, tubing pressure, and differential pressure between them. The DCS-NG also has the ability to operate as a Dual/Single Valve Timer or a High-Low Controller. The DCS-NG allows the operator to achieve the most efficient production without guesswork. With many communication possibilities, the operator can generate reports and graphs which allow him to troubleshoot, fine tune, and maximize production.

Plungers are designed to act as an interface between the gas pushing and the fluids being lifted to the surface within the tubing string.  Padded plungers are designed to compensate for any inconsistencies in the tubing, thus creating a consistent seal against the walls of the tubing and maximizing efficiency.  Bumper Springs are used to protect the tubing and plunger from impact damage.
